ArduinoDueParallel

Library to enable the External Memory Bus/Static Memory Controller on the
Arduino Due board. It's more of an external memory interface than a true
parallel port.

The DUE board pins out the data bus on the extended digital headers along with
the control signals NCS1 and NWR. Some of the address signals are connected to
the PWM pins (A0-A5), but a full address bus is unavailable. There is also
conflict between the SS1 pin for SPI and the NRD signal used for the parallel
bus. In short the hardware wasn't designed for use with external parallel
memories.

The library does allow connection to some of the lower resolution LCD
controllers that used index addressing and can speed up read/write times
considerably.

To use this library, place the files in a folder under the libraries directory
in your sketches folder.
